Filed: 1972-01-31
Abstract: 1372336 Component insertion apparatus INTERNATIONAL BUSINESS MACHINES CORP 31 Jan 1972 [1 March 1971] 4352/72 Heading B3A [Also in Division B8] Apparatus for positioning components 35 on a panel 68 comprises means for releasing a component from each of a plurality of component stacks, means operable with the releasing means for moving a panel to a component receiving position, Fig. 2 (not shown), and means 27 for guiding the released components to predetermined positions on the panel . The releasing means includes two sets of parallel rods 45, 48 movable through holes 47, 50 in members 28 of a component guide assembly 27, and the panel moving means includes a cam follower 75 which co-operates with a cam 17 to cause movement of a bracket 62 towards or away from assembly 27. Magazines 34 are placed in a holder assembly 32 in a loading pan (90), Fig. 4 (not shown), which is adapted to be received by pins 38 until the pan rests on guide assembly 27. End plate assemblies, which include end plates 14a, 14b, movable rods 13, and support bars 15, 16, are moved to the left (as viewed in Figs. 1, 2), and the loading pan is removed. This allows components in each magazine to move downwards until leads 36 of the bottom-work components of each stack straddle rods 48, Fig. 3 (not shown). A panel holder 65 is drawn back from the and a circuit panel 68 is assembly 27 inserted. The end plate assemblies are then moved to the right causing cam 17 to move under follower 75 thus raising bracket 62 and panel holder 65 towards guide assembly 27. This movement causes withdrawal to the right of upper rods 48 and insertion of lower rods 45 under the lower components in the magazines 34. The end plate assemblies are then moved to the left again such that rods 48 contact components 35 above those components supported by rods 45 simultaneously with the withdrawal of rods 45 and consequential inserting of leads 36 into corresponding holes in board 68. In the particular embodiment the surface of cam 17 has slight depressions 97 formed therein to produce vibrations to aid seating of the components. The bracket 62 is lowered when the end plate assemblies are moved to the extreme left and the panel holder 65 can be subsequently withdrawn. The assembled panel and components can be removed from the holder and further processed, e.g. securing of component leads to the panel. The magazines can be readily moved to different positions in the holder, corresponding to different positions on the panel, to facilitate the assembly of various circuit arrangements. The magazine matrix may be larger than that shown and even allow the insertion of components in several panels during a single insertion cycle. Alternatively, the apparatus may be modified, or used in conjunction with another apparatus, to assemble a panel in two operations.

Title: Improvements in the manufacture of derivatives of cellulose
Filed: 1933-02-16
Abstract: Oxyalkyl ethers of cellulose are prepared by reacting cellulose at temperatures of the order of 120 DEG  C. or more with gaseous alkylene oxide as the sole etherifying agents.  The reaction may take place under normal or elevated pressure and it is preferred to have present a small amount of a weak acid or of caustic alkali or other basic substance.  Suitable oxides are, ethylene oxide, propylene oxide or butylene oxide.  As an alternative to the presence of an acid or alkali during etherification, the cellulose may be pre-treated, e.g. as described in British Specifications 249,173, 263,938, [both in Class 2 (ii)]; 407,018; 414,751, [Group VIII], or in French Specification 565,654.  The etherification is preferably carried on until an oxyalkyl cellulose having a content of at least one oxyalkyl group per unit molecule of is obtained.  The ethers prepared above may be acetylated and thereafter made into filaments, films &c. by wet spinning processes as described in Specifications 177,868, 179,234, [both in Class 2 (ii)], 340,324, 340,325, 340,436, 340,437, 343,062, 405,619, 405,676, 405,692, 406,337, 406,985, 407,351, 407,673 and 412,601, or by dry spinning processes as described in Specifications 165,519, 198,023, 203,092, 300,998, 325,233, [all in Class 2 (ii)].
